Data Consistency in Transactional Business Processes

Current research about transactional workflows focuses on replicating the atomicity property for business processes using long running transactions with compensation as a replacement for rollback. But there is no standard way to guarantee data consistency between concurrent long running transactions yet. Isolation of different business processes most often is not a practical solution. To ensure reliability nevertheless, we present a generic method to detect consistency conflicts caused by the resource accesses of concurrent workflows. The method can easily be integrated into a Business Process Management System.
